Hand held surgical device for manipulating an internal magnet assembly within a patient
First Claim
1. A device for manipulating a magnetic coupling force across tissue comprising:
- a magnetic field source assembly comprising a first magnetic field source for providing, in use, a magnetic field across tissue, the first magnetic field source providing a magnetic coupling force between the first magnetic field source and an object providing a second magnetic field source;
a positioning assembly operatively connected to the magnetic field source assembly for adjusting an elevational position of the first magnetic field source, the positioning assembly having a driver for adjusting the elevational position of the magnetic field source assembly and an actuator for moving the driver;
a magnetic coupling force monitor; and
an outer housing containing at least the magnetic field source assembly, the outer housing configured to allow elevational adjustment of the magnetic field source assembly within the housing;
wherein the magnetic field source assembly further comprises;
a magnet housing,a magnet support, andthe first magnetic field source comprises at least one magnet, the at least one magnet being held by the magnet support and suspended within the magnet housing.

Abstract
A device for manipulating a magnetic coupling force across tissue in response to a monitored coupling force is described. The device includes a magnetic field source assembly, a positioning assembly operatively connected to the magnetic field force assembly, and a magnetic coupling force monitor. The magnetic field source assembly includes magnets that provide an external magnetic field source for providing a magnetic field across tissue. The positioning assembly adjusts the position of the magnetic field source. The magnetic field creates a magnetic coupling force between the external magnetic field source and an object positioned in use in a patient during a procedure, wherein the object has or is associated with an internal magnetic field.
